6 Claims.

This invention relates to the mounting of spinning and twister rings on the ring rails of v spinning and twister frames. Since the construction involved is essentially the same in both types of machines, the term spinning rings will hereinafter be used in a generic sense to include twister rings, and the term spinning frames will be understood to include twister frames.

The invention aims to improve the mounting of spinning rings with a View to facilitating the replacement and repair of these devices, while at the same time holding them securely in their normal operative positions.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawing, and the novel features will be particularly pointed out in the appended claims.

In the drawing,

Figure 1 is a plan View of a portion of a ring rail with a ring mounted therein, and illustrates features of this invention;

Fig. 2 is a sectional view on approximately the line 22, Fig. 1; and

Fig. 3 is a sectional view on a larger scale illustrating the manner in which the ring is secured or released.

In the drawing a ring rail of a conventional type is shown at 2 and a ring mounted in said 90 rail is illustrated at 3. It will be observed that the rail has a circular aperture 4 formed through it and that the shank of the ring includes a cylindrical portion 5 to fit snugly into said aperture and center the ring in the rail, the ring also including a flange 6 which rests on the upper surface of the rail.

Below the shoulder 5 the shank of the ring is provided with a frusto-conical portion 7, best shown in Fig. 3, which is utilized by the present invention in fastening the ring in its operative position. For this purpose two clips 8 and 8' preferably are used, each being a duplicate of the other, and the two being located at diametrically opposite sides of the ring.

Referring more particularly to the construction shown in Fig. 3, and illustrated also at the right of Figs. 1 and 2, it will be seen that the clip 8 consists of a piece of sheet metal, preferably of spring steel, or some equivalent resilient material, provided with two rounded points 9-9 at one end to bear on the tapered or frusto-conical surface "i, the metal at the forward edge of the clips being cut away between these points. A screw ID, projecting through a hole l2 in the clip and threaded into the ring rail, secures the clip 8 normally in its operative position, as illustrated in Fig. 2, where it bears against the lower side of the rail. It will be observed that the lower margin of the aperture 4 in the ring rail is bevelled, and that the junction of this bevelled surface with the lower face of the ring rail forms a shoulder l3, Fig. 3. After the clip has been placed in position, and as it is swung upwardly by the act of threading the screw Iii inwardly, the upper surface of the clip is brought into contact with this shoulder, and as the screw is tightened up, the clip rocks or fulcrums on the shoulder, acting as a lever. During this movement the inner ends or points 99 of the clip, which are resting on the inclined surface 7, are 15 being forced downwardly, and they therefore draw the ring firmly down into its seat. This action, however, is produced yieldingly due to the resilient nature of the clip 8.

The other clip or lever 8 at the opposite side 20 of the ring is like that just described, is secured in the same manner, and produces the same action on the ring. The corresponding parts of this unit are designated by the same, but primed, numerals. 25

Whenever it is desired to remove the ring, the two screws I!) and ID are backed out and permit the clips or levers 8 and 8' to drop out of position. Or the holes in these members may be made large enough to permit them to 30 be slid backwardly out of contact with the ring when the screws have been backed out a certain distance. The ring may then be repaired and replaced, or a new one substituted for it. The invention thus provides a very simple, in expensive, but positively arrangement for looking spinning rings in their operative positions.

The particular ring shown is of the solid type, but some rings are equipped with a base or holder in which they are removably mounted. 40 So far as this invention is concerned, the base corresponds to the shank of the ring illustrated, and the two constructions are, therefore, equivalents so far as the matter of mounting them in a ring rail by the present method is con- 45 cerned.

While I have herein shown and described a preferred embodiment of my invention, it will be evident that the invention is not limited to the exact details of the construction shown. 50

Having thus described my invention, what I desire to claim as new is:

1. In a spinning frame, the combination of a ring rail having an aperture therethrough, a ring seated on said rail and having a portion 55 thereof projecting into said aperture, means for fastening the ring in said position, including a lever fulcrumed on the lower edge of said aperture, and means for holding said lever in its operative position.

2. In a spinning frame, the combination of a ring rail having an aperture therethrough, a ring seated on said rail and having a portion thereof projecting into said aperture, means for fastening the ring in said position, including a lever for engaging the ring and mounted on the lower side of the ring rail to swing toward and from the plane of the rail, and means for holding said lever in its ring locking position.

3. In a spinning frame, the combination of a ring rail having an aperture therethrough, a ring seated on said rail and having a portion thereof projecting into said aperture, a lever fulcrumed on the lower edge of said aperture and having an end portion arranged to engage the shank of the ring, and a screw threaded into said rail and acting on said lever to swing said end portion downwardly and serving thereby to lock the ring in its operative position.

4. In a spinning frame, the combination of a ring rail having an aperture therethrough, a ring seated on said rail and having a shank portion thereof projecting into said aperture, and means for fastening the ring in said position including a lever fulcrumed on a surface of the ring rail at the lower side thereof and having a part engaging said portion of the ring, and means for holding said lever in its ring locking position.

5. In a spinning frame, the combination of a ring rail having an aperture therethrough, a ring seated on said rail and having a shank portion thereof projecting into said aperture and provided with a shoulder, and means for fastening the ring in said position including a lever mounted to rock on the lower side of the ring rail and having a part to bear on said shoulder, and screw threaded means for operating said lever to cause it to lock said ring in its operative position.

6. In a spinning frame, the combination of a ring rail having an aperture therethrough, a ring seated on said rail and having a shank portion thereof projecting into said aperture and provided with a shoulder, a resilient member mounted on the lower side of said ring rail and having a portion located between said shoulder and the margin of said aperture for fastening said ring in its operative position, and screw threaded means mounted in said rail for operating said member.
